Abstract: A method of detecting passage by an individual carrying a mobile device past an impediment operably connected to an access control is provided. The method including: detecting positional data of a mobile device; transmitting an access request from the mobile device to an access control operably connected to an impediment; detecting at least one of a sound from the impediment and a motion of the impediment; and determining that an individual carrying the mobile device has moved past the impediment in response to at least one of the sound from the impediment, the motion of the impediment, and the positional data of the mobile device.

Abstract: The present invention is a universal workpiece holder that includes a unique positioning hub and a plurality of clamping devices for clamping a variety of annularly shaped workpieces having different interior and/or exterior diameters. The positioning hub includes multiple sets of spokes, wherein when a particular set of spokes aligns with the clamping devices, the workpiece holder is able to secure a particularly sized annulus without distorting it. Moreover, upon rotating the positioning hub about its center and aligning a different set of spokes with the clamping devices, the workpiece holder is able to secure a differently sized annulus. Each set of spokes corresponds to a certain sized annulus, thereby eliminating the need for an independent workpiece holder for each differently sized annulus.
